COMPUTING AND RECORDING MACHINE.

Specification of Letters Patent.

Application filed June 1, 1909. Serial No. 499,450.

ing is a specification.

The object of the present invention is to provide a machine especially adapted to be used in banks and similar institutions by which checks or other documents relating to money may be stamped with the amount paid, or received, thereon, by which a record may be obtained of all the individual sums so paid or'received, and by which a separate total may be independently obtained of any desired portion of such payments, or other sums.

The invention also resides in the novel construction, combination and arrangement of parts hereinafter. fully specified and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a longitudinal section of the apparatus; Fig. 2 is a vertical section near the front end thereof; Fig. 3 is a broken horizontal section on 'the front, portion of the machine; Fig. 1

l is a 'plan View of the machine; Fig. 5 is a vertical section on the line 5-5 of Fig. 1; Fig. 6 is an enlarged detail rear view of the operating mechanism; Fig. 7 is a transverse section through the operating shaft; Fig. 8 is a detail side view showing the bearings for the two series 'of totalizing wheels and the connection between them; Fig. 9 is a 4 similar View showing the same parts in a different position; Fig. 10-is a diagrammatic view illustrating said connection; F g. 11 is an enlarged section-through atotahzing shaft; Fig. 12 is a broken longitudinal section thereof; Figs. 13, 14c, 15, 16 and 17, are views, similar to Fig. 11, showing the parts in different positions; Fig. 18 is a transverse section through totalizing wheels detached; Fig. 19 is 'a side view of the same; Fig. 20 is a view of the other side of the same; Fig. '21 is a side view of a collar.

which carries a latch; Fig. 22-is a perspective View, of the sleeves in the end of an arm, the arm itself being omitted; Figs-23 is a perspective view of an inner sleeve on a totalizin shaft.

Referrmg to the drawing, 1 indicates. a base, and 2' a casing secured thereon, within which casing are contained the operating parts of the machine. 3 indicates an vupper, and 4: a lower, guide plate through which plates slide vertically the stems 5 of operating keys 6. These stems and keys may be arranged in any desired number of columns,

there being nine keys in each column, numbered in order from 1 to 9. Each key is normally pressed upward by a coiled spring 7 around its stem pressing against a collar 8 on the stem. The lower portions of said stems are bent at right angles, or horizontally, as shown at 9, and then again downward, as shown at 10, they being given this form in order to bring the lower ends of all of the stems of each column close together. Said lower ends pass through holes in a guide plate 11 suitably secured upon the frame.

12 indicates an operating handle on the end of an arm 13, secured to a transverse shaft 14, rotating in bearing 15, said shaft a segment 19 formed with an arcuate slot 20.

Engaging the slot 20 in said segment 19 is a pin 21 on the end of a link 22 pivotally attached at its rear end to the endof an arm 23 secured to one end of a rock shaft 24 extending across the machine, to the other end of which rock shaft is also secured an arm 25 similar to the arm 23, the outer ends of said arms being connected with each other by a cross bar 26. When the operator actuates the operating handle 12 by moving it downward and toward the front, the arouate segment in which is formed the slot 20 moves downward and rearward, thereby freeing said link 22, so asto permit said rock shaft 24 to rock and the cross bar 26 to move rearward. Said cross bar 26, in the normal position of the machine, engages recesses 27 formed in the rear edges of arms 28, one for each column, said arms being loose on said l a frame 33. Each slide piece is formed on the under side of its front end with a rack 3 1, whlch engages a gear wheel secured Patented Sept. '7, 1915.

to the side of a recording wheel 36 loose on afixed transverse shaft 37. Secured'to each recording wheel is the outer end ofa coiled spring 38', its inner end being secured togt lie fixed shaft 37.. Said spring is so wanna that it tends constantly to turn the recording wheel 36 rearwardly at the top, andthey do on account of the force of the spring 38. The extentof this rearward movement,

and therefore also the angular position to 'which'the recording wheel is moved with said rearward movement of the slide, is dependent upon. the particular key operated, the slidepiece being variably arrested by a stop 34 thereon striking the lower end 10 of the key stem.

Around .the shaft 14 is a coiled spring 39, which is sufliciently powerful, not only to return the operating handle to its normal position when released, and thereby through the-slotted segment 19 and the pin 21, to return the slide pieces 31 to their normal position, but also to ovencome the tension of all the coiled springs 38 of the recording wheels.

Each recording wheel 36 carries upon its peripheral face a series of marking devices or dies 40 for marking characters, namely, the dollar sign, zero, and the numerals from.

1' to 9. All of the dies of the rollers are inked by inking rollers 41 as the rollers rotate. The casing 2 is formed with a horizontal slit 42 forming a guide for the insertion of a check, the leaf of a pass book, or otherjpaper which is to be marked. EX-

tending transversely under the lowest portion of allof the recording wheels is a bar 43,, having under each wheel a raised portion 44 with a roughened upper surface, said bar being supported upon a lever 45,

5 pivoted at its front end upon a suitable standard 46, said lever being normallypulled upward by a coiled spring 47. The free end of said lever carries a roller 48 which is adapted to be engaged by a pawl 49,pivoted at 50' upon the slotted segment- 19, its rearward movement being prevented by a shoulder 51 formed on said segment, although it is permitted a forward movement, away from said shoulder.- A spring 52 normally presses the pawl against said further movement of the slotted segment,

the pawl 49 actuatesthe roller 48 and depresses the lever 45 and, when said pawl passes said roller, the spring 47 retracts the .pawl 70 passes said arm 68.

lever and thereby moves the roughened blocks 44 against the under side of the check or other paper, and forces the latter against the die 40 on the recording wheel to thereby mark the check. The serrations of the roughened block 44 produce corre sponding markings in the paper which are rendered more prominent by means of the inking of the dies.

Each slide piece is formed with an upward extension 55, bent forwardly at the top to form a type carrier 56, on which are a series of type 57, each having a stem 58,

slidable vertically in said carrier and normally depressed by a coiled spring 59. The type of each series are adapted to print the numerals 0 to 9, and they are arranged at intervals equal to the successive increments of the distance traveled by theslide piece on the depression of the keys 6. Said type 57 face upward,and above themis extended an inking ribbon 60, above which is a platen 61, between which platen and the inking ribbon 60 is adapted to be interposed paper 62 fed from a roll 63 and passing between said platen and a guide roller 64. \Vhen, by the operation of the keys of the several columns, the corresponding type have been moved beneath the center of said platen, the lower ends of all of the stems of the type thus brought into printing position are adapted to be struck by a transversely extending hammer 65 carried on the free end of a lever 66 pivoted on a transverse shaft .67 and having a rear arm (38 normally drawn down by a spring 69, the spring being of sufficient tension to prevent the hammer dropping too far, while at the same time being insuflicient to raise the hammer into the path of the lower ends of the type stems when they are moved by the movements of the slide pieces 31. In a recess in a collar mounted on the shaft 14, is pivoted a pawl 70, which. is arrested in its rearward movement by a shoulder 71 on said collar. When the operator actuates the operating handle 12, said pawl 70, being prevented from moving forwardly by said shoulder. 1, engages the end of the arm 68 of the lever 66 and moves the same for wardly against'the action of said spring 69, and thereby lowers the hammer 65 until said lVhen said arm is released from said pawl, it descends under the action of the spring 69 and moves the hammerrapidly against the lower ends of the stems of the type, thereby making an impression upon the paper. The platen is turned by hand to move the paper to the proper position for the next impression, the

distance through which the paper moves by on its pivot into a groove 53, but will fall by gravity and pass the arm 68 when the handle is at rest.

Pivoted at 75 upon an extension 76 of the rear of the guide plate 11 are plates 77, each having a slot 78, through which pass all of the stems?) ofthe keys 6 of the corresponding column, each stem having a pin 79 extending transversely over said plate '77. Each plate at its front end extends over the tops of three vertical additional or terminal keys in the form of rods 80, 80, 80", slidable vertically in the guide platell, and arranged longitudinally of the machine, and

in front of the-key stems, but to one side thereof, each rod being pressed upward by a coiled spring 81. Extending laterally from each rod, below said guide plate 11 is a pin 82.

The first rod 80 for each'of the columns is for the purpose of preventing any move-- ment of the recordi'ng wheels into a printing position unless one of the keys 6 has been, operated, so that, if the operating handle is actuated without first depressing one of said keys 6, the serrated blocks 44 will be moved into blank spaces 83 in the register wheels, and no wear or damage can be thereby caused to the marking devices of said wheels. The top of each of said front rods 80, except the one on the extreme right, is formed with an extension 84: to the right, which extends over-an extension 85 to'the left formed upon the top of each of said front rods 80 except the one to the left. The

effect is that, when any keyof any column is depressed, the pivot plate 77 of that col-- umn is depressed, andthereby the front rod 80 of said column is also depressed, and all the front rods of the columns to the right are likewise depressed, but not of those to the left. Each plate 77, however, extends over the extension 86 of the front rod tothe left, so that, upon the depression of any key of any column, the front rod 80 next on the left is also depressed, but none of the other front rods 80 on the left, the object being to permit the slide piece 31 on the left of the column, a key of which has been op-- erated, to slidepast said controller rod 80 into the position in which the dollar mark on the recording wheel corresponding to I said slide pieceon the left can be printed.

For a similar purpose. there is provided on the extreme left of the series of six slide pieces 31 a slide bar 87, especially for marking the dollar mark, controlled by a stop rod 88 in line with. the front rods 80 of the columns of keys. Behind'said front movable stop rod 88 is a stationary stop rod 89 which always arrests the slide bar. 87 on the extreme left in the position in which the corresponding recorder wheel records the dollar mark.

The second row of'jstop rods 80 is for the purpose of arresting ,the slide pieces 31 in the positions in which the corresponding register wheels register the dollar mark. a

column, all the second stop rods on the right are depressed, so that the register wheels on the right can move past the dollar mark. Each pivoted plate 77 is, however, 4

as shown at 90, cut away on the left,- opposite to the extension 8 1 of the second stop rod 80 on the left of said plate, so that,-

when the pivoted plate 77 is depressed, it

clears the extension on the right 8 1 of the.

second rod 80 immediately to the left, so that the register wheel immediately on the left can move to the position to make the dollar sign.

All the register wheels on the rightof the column a key of which is being actuated are free to move so as to be arrested by the third row of stop rods 80", which are forthe purpose of stopping the register wheels in the positions in which they will mark a zero sign. Consequently, if, for instance,in. the third column, the numeral key 5 be depressed, and no other key be depressed the dollar sign will. be marked by the register wheel corresponding to the second, column, the numeral 5 will be marked by that corresponding to the third column, and

the zero sign will be marked by all the columns to the right.

' In order to prevent any key being actuated until after the completion of the operation effected by the depression of any other key in the same column, there is provided, for each key of that column, on a shaft 91 for each column extending from front to rear of the machine, a locking segment 92 (Fig. 6) having a circular portion 93, a recess 94 and a. projecting arm 95. Said arm is adapted to be engaged by a pin 96, secured upon said -key stem, so that, when the stem is depressed, the shaft 91 is rocked,

thereby moving the circular portions 93 of all of the other segments 92 beneath the said pins 96 upon the keys of the same column,

and preventingthe depression of said keys until the locking shaft 91 is returned to its original position. It is also necessary to i hold the operating keys which are first operated down, in their operative position, until all the necessary keys have been depressed before the printing operation takes place. To do this, there is secured .upon the end of each shaft 91 a vertical sleeve 100 in which can slide a stem 101 having at the distance between the columns, with circular' top a head 102 which limits its downward movement, and at the bottom a dog 103. Said stem is normally depressed by a' spring 10 1 between said dog and sleeve. Upon the operating shaft is fixedly secured. a sleeve 105, the main portion of which'is eccentric or cam-shaped in cross section, that is, having a normally uppermost part 106 of less thickness than the remainder. Said sleeve is formed, at intervals corresponding with the rings or flanges 107 each formed at the top, or that part which is radially in line with the thinnest portion of the sleeve, with a notch or opening 108, through which can passthe dog 103. Immediately on the right hand side of each flange looking from the front, or on the left looking from the rear,

, as shown in Figs. 5 and 6, said sleeve is also formed with a rib-like .extension or thickening 110, located immediately above the thinner portion 106 of the sleeve, said extension forming a true circle with the main portion of the sleeve. Before a key is depressed, the parts are in the position shown in Fig. 5 and also on the left-of Fig.

6, in which the dog 103 is on the left of the ring 107 looking fromthe front. When the key is depressed the pin 96 of its stem, engaging the arm 95, rocks the shaft 91 and causes the dog 103 to pass through the notch or opening 108 in the ring 107. Said dog is formed with a beveled advancing lower side 111, and when this side impinges upon the bottom of the notch 108, and also upon the top of the rib ll0ysaid dog is pressed upward, as the shaft 91 is turned, until the dog pa'sses over said rib 110, and thereupon the spring projects the dog into the position shown on the right of Fig. 6 and in Fig. 7. In this position it is locked until the operating shaft is turned. .lVhen the operator has depressed the numeral keys of the several. columns for the purpose of printing a row of figures, all the keys so depressed are by the above mechanism locked until the operator actuates the operating handle. In moving the handle through even a very small distance, in the" operation of the same, he immediately locks all the other keys, which have not been actuated, so that they cannot be actuated, for, by moving the handle and I rocking the shaft he moves all the notches remain in this position until the operating handle has been released and the operating shaft has been rocked back to its original position. While the said shaft is so rocking back, the lower ends of said dogs ride upon the raised portions or ribs 110 until said dogs arrive at the notches or openings 108 in the rings, whereupon on account of the upward pressure of the springs 7, they immediately pass through said notches to their original position, shown in Fig. 2.

For the purpose of accumulating, or totalizing, the amounts so printed, there is formed on each slide piece 31 a downwardly facing rack 112, which is adapted to engage a gear wheel 113 which is looselymounted in a groove 114 formedin a sleeve 115 which rotates on another sleeve 116, which can rotate loosely. on a shaft 117 extending transversely of the machine. When any numeral key is depressed, and the operating handle has been operated to print the corresponding numeral, from the movement of the slide piece which moves the register wheel to any required number, a corresponding movement takes place in the gear wheel 113 owing to its engagement with said rack 112. If now a numeral key in the same column be again depressed the slide piece 31 will move a sec- 0nd time, and the gear wheel will be again advanced,'so'that the total advance which it has made will correspond to the sum of the two numerals corresponding to the numeral keys depressed. The samewill be true however many times the numeral keys in said column are operated and the operating handle is actuated to obtain a record thereof.

Omitting for the present, the description of the mechanism for carrying or transferring from one such wheel to another, it will first be explained how this total is obtained in the machine. This .is done by providing a lower rack 118 facing upward, and similar to, and co-extensive with, the upper rack 112. As will be presently described, pro- 2 I vision is made for shifting the shaft 117 by means of a small handle 119, to a lower position. A gear wheel 120 is formed on the sleeve 115, and-is rotated with 'the gear wheel 113, by means of a pawl 121 carried on a radial extension 122 of said gear wheel 113. In the lower position, said gear wheel 120 can engage said lower rack 118 for obtaining totals. When the operator desires to obtain a total of the numbers registered by the machine, he so actuates said handle 119. The gear wheel 120 is now in the lower position adapted to engage the lower rack slide piece 31 moves rearward, and the rack 118 engages the gear wheel 120 and rotates the same. The extent of rotation, and therefore also the extent of the rearward movement of the slide piece 31 depends upon the numerical distance, counting from zero, through which the gear wheel 120 has been rotated, or stands, at the time the operating handle is actuated. For instance, supposing that the operator depresses, in a column, first, the numeral key 1, then the numeral-key3, and then the numeral key 5, the gear wheel will have. rotated through the same angular distance as when the register wheel has rotated to print the numeral 9. It will then be in the position shown in Fig. 13. 'When the rack advances, by reason of the movement of the operating handle, it turns the totalizing 'wheel in the reverse direction to that in which it was turned when totalizing; in other words, it causes the totalizing wheel to subtract, and this reverse movement continues until a pin 125 extending laterally from the side of the totalizing wheel (Fig. 13) engages a pin 126 extending radially from a sleeve 127, hereinafter more fully described, and, which at this time, and normally, is

held in a fixed vertical position. Thereby the rotary movement of the gear wheel 120 is arrested, and consequently the rearward movement of the rack 118, and therefore the slide piece is also arrested. The arrangement is such that the arrest occurs in a position when the type for printing the numeral 9 is in position for printing upon the recording sheet. The gear wheel'120 will then be in the position shown in Fig. 13; In the continued movement of the operating handle said printing is effected, and the slide bar is released and returns. Upon returning the slide bar, the totalizer again returnsto its original position, registering the total, of 9.

A second series of totalizing wheels 113 and 120 is also provided, operated in precisely the same manner as the first series,

namely,-by an upper rack 112 for addition or totalizing, and 'a lower rack 118' for obtaining a record of the total. By a suitable arrangement also, not here shown, one of these series may be made generally accessible and used for temporary work while, the other may be preserved from general accessibility, and retain a permanent record of the total.

Since the totalizers themselves form no part of the invention no further showing of their operating parts is made than is actually necessary to make them operative, but it is necessary to provide that the means for carrying out the operations common to totalizers be concealed and inaccessible to the ordinary operator in. the case of the set of totalizers, correlated with the book printing the plates 132 nearer the front of the ma-.

chine passes the shaft 117 upon which are mounted the series of totalizing wheels 113, while through the plates 132 toward the rear of the machine passes the shaft 117,

upon which are mounted the rear series of totalizing wheels 120. Said shafts project at one end through the respective plates to form handles 119,119, and are connected by a link 135. This arrangement is illustrated diagrammatically in Fig. 10, which 'indicates the position of the parts when thefront series of totalizing wheels are in their upper position and therefore arranged for totalizing. It will be seen that, .on-account of the relation which the length of the link bears to the distance between the two circular bearings, when the 'front totalizing wheels are in the upper position the rear totalizing wheels can'take only an intermediate position, adapted to engage neither the upper nor lower rack. If now the front totalizing wheels are lowered into the position for recording, this does not affect the position at that time of the rear totalizing wheels, which are still in the intermediate or inoperative position.

Suppose now that it is desired to operate the rear series of totalizing wheels, as. for making an independent calculation or totalization of a series of numbers, the rear totalizing wheels are moved to the upperposition. The link,

record. It will be seen that by this contrivance only one series of totalizing wheels are in an operative position at any one time, and that the position of either series is not afi'ected by the movement of the other series from the totalizing to the recording position With the above arrangement it is necessary to guard against the possibility of being able to move the series of totalizing wheels so that they would not be engaged by either the upper orthe lower rack, then to operate the handle so as to move the slide piece and the racks formed thereon, and then to again return the teeth of the totalizing wheels into engagement with one of said racks, the effect of which would be to produce an erroneous computation. To prevent this, there is provided a slide 140 having a vertically slotted rear end 141 engaged by the transverse shaft 117 which slide is formed with" three longitudinal or horizontal slots 142 .all connected with each other at their rear .ends.

positions. Since the several positions of the front shaft 117 correspond accurately with the positions of the rear shaft 117 it follows that neither the front nor the rear series of totalizing wheels can be moved into such a position that neither of them will engageone of the racks upon the slide piece, and the operating handle operated.

It is necessary to remove from the path of the slide pieces 31 the three .front rows of controller rods 80, 80, 80 when it is desired to print the totals oneither totalizing mechanism. For this purpose, to the disk 132 for the. front totalizing mechanism there is pivotally attached a link 123 having an upper slotted end 124 guided by a pin 134 and adapted to engage a rearward extension 128 of the plate 77. When the said totalizing mechanism 113 is lowered, to record the total, said link being attached on the opposite side of the diSk"tO the handle, is simultaneously raised, and thereby the rear extension of the plate 77 is raised and the front end depressed, thereby depressing all of the front controller rods 80, 80, 80" and permitting the slide pieces 31 to pass the same in the recording movement. A similar provision is made for the rear or temporary totalizing mechanism.

Attached to the disk of the front totalizing mechanism is a cam plate 129, the lower end of which is adapted to engage the pin 133 upon which is mounted the roller 48. When either series of totalizing wheels'is lowered for the purpose of recording the total, said cam being moved around with the disk, engages said pin, and moves the roller 48 out of the path of the pawl 49 so that the operating handle 12 can be operated without said pawl engaging said roller. The cam is formed in its edge with two recesses or depressions, the first one 136 being arranged to engage said pin 133 when the disk is in the intermediate position, and the second recess 137 when the disk is in the lowermost position. Said pin engaging said recess serves to center or hold the parts in Iplace.

, pon the transverse shaft 138 is pivoted a lever 139 carrying at its front end a shutte'r 109 its rear end being adapted to be engaged by a cam 99. When the front totalizing wheels are moved, either to the intermediate or to the lowermost position, the rear end of said lever 139 is depressed, so that the shutter carried by .the front end closes the front end of the slot 42 to prevent the insertion therein of a check, or other paper.

V t willalso be observed that the can 129 positively prevents printing from the check 'books can be fraudulently printed without at the same time accumulating the amounts printed thereon.

The details of construction of the totalizing wheels are illustrated in Figs. 19 to 23. Fixedly secured upon a computing shaft 117 area series of collars 144 in each of which is pivotally mounted a latch 145. Intermediate between said collars and fixed upon the shaft 117 is a second series of col lars 146. Rotatable about the collars 146 and also about the shaft are a series of sleeves 116 each having an arm 147 from which extends laterally on the right a pin 148. Rotating on said sleeves 116 is a sleeve or wheel 115, formed on the left hand side with ratchet teeth 149, and on the right hand while the gear wheel 120 formed on the right of the wheel is adapted to be rotated by the lower rack 118 in the opposite direction to the gear wheel 1'13. Bormed upon the gear wheel 11.3 is the arm 122 which carries a spring-actuated pawl 121 ada ted to engage the-ratchet teeth 149 of the w eel 115. Consequently, although the upper rack 112 rotates the gear wheel 113, first in one direction, and then in the opposite direction in the return movement of the rack, since the gear wheel 113 imparts movement to the wheel only by means of a sprin actuated pawl, said movement is imparted only in the advancing direction of the rack, and not in the return movement thereof. Corresponding, therefore, to each distance through which the rack 112,is reciprocated upon the actuation of the operating handle, the wheel 120. is rotated in-a forward direction a corresponding angular distance, and these angular rotary -movements are accu- 60 shown in Fig."16.

mulated in the successive reciprocations of the rack.

It has been already explained how the angular distances through which the Wheels 120 have thus been rotated from the zero position are recorded by means of the lower rack 118, and, after being so recorded, said wheels are left in the same angular position as before, thus permitting the accumulation to continue after making such a record.

It now remains to be explained how the transfer is made from one wheel of the series to the next on the left, when to the number registered by the first wheel is added, a

.number which makes the total more than 9. Upon the shaft 117 adjacent to the collar 144 is rotatably mounted an arm 150, normally rotated in the same direction as the forward rotation of the wheels by a coiled spring 151 secured to said arm and to one of the collars 146. Through the end of said arm passes loosely a shaft 152 carrying, at one side of said arm, a sleeve 127 from which extend inwardly, or toward'th-e fixed shaft 117, teeth or lugs 126, 155. On said shaft 117, on the other side of said arm, is

secured a sleeve 156, from which extends, at

about a right angle to the tooth 126, a tooth 157. Extending to the left from each of the wheels 116 is alpin 125- which, when'the wheel 115 has been rotated through an angular distance corresponding to the registra tion of the numeral 9, is brought into such a position that it engages the leading or ad 3 vancing tooth 126. 'In like manner from ,the right hand side of said wheel .116 extends laterally a pin 148 in alinement with the pin 125 on the left. These pinsand the arms carrying the same, move in slots 40 1.61, 162, formed in the wheel 115 when the wheel 115 has moved to such a position as to register the numeral .9, the rear ends of said slots have brought said pins to the position shown in Fig. 13. In this position, the

pin 125 on the left is adapted to engage the tooth 126, extendingdownward from the sleeve 127. On the subsequent advance of the wheel 115, and therefore also of the sleeve 116, with the pins carried thereby,

said pin 125 engages said lug or tooth 126 and advances the same into the position shown in Fig. 14. The lug or tooth 157 carried by the other sleeve 156 upon the shaft 152 is thus moved to the upper position as.

shown in said figure, and is in the path of a pin 159 extending laterally from the upper rack. Therefore in the return movement of the upper rack, said pin moves the arm 150 'rbarwardly upon the shaft 117, as

Theffirst effect of the rearward movement. of-the rack is to raise 'a pawl 164 -pivotally carried upon theshaft 152 and' normally depressed by a spring 165, but adapted to be-raised by means of a tooth 166,on the sleeve 156 engaging a pin 167 extending laterallyfrom thepawl. The

end of the pawl is thereby raised from off the teeth 120. This upward movement is arrested by the tooth 126 abutting against a pin 154 upon the arm 150. The rearward movement of the rack can now therefore have only the effect of moving rearwardly the arm 150, and this it does, carrying with it the pawl 164, until the arm has been rotated through such an angle that the pin 159 'arrives at the position shown in Fig. 16 and leaves the upper tooth 157. By the force of the spring 165, the pawl immediately drops into-"engagement with the teeth 120,

and immediately afterward the coiled spring 151 returns the arm 150 to its normal position, thereby causing the wheel 120 toadvance .one-tenth of a revolution.

The inner edge of the free end of the pawl 164 is formed to enter between two adjacent teeth of the wheel 120, thereby serving to center said wheel accurately, whenever its angular position has been changed.

Since the transfer to, and accumulation by 1 on, the next wheel to the left is made of the first wheel to the left. It is in order to provide against such a contingency there is formed upon the sleeve 156 the tooth 155 extending inwardly, but at an angle with the direction of the arm 126, and in such a position that, when the pin 125 extending from the right to the next wheel 120 on the left has been brought to the 9 position, said tooth 155 is immediately behind said arm. With this arrangement, if, say, three wheels in succession on the left of the wheel which is being operated all stand at the position 9, the three teeth 155 of said wheels are immediately behind the pins 148, and the result is that, when the first wheel is operated, and is advanced from the 9 to the zero position, all the other wheels are likewise advanced through the greater part of the distance between the 9 and 0 positions. They are then centered in the proper position by the pawls 164, the free ends. of which enter between the gear teeth of the wheels 120 and thus complete the advance.

In order to hold the arm 126 against rearward movement there is pivoted in the collar a spring latch 145, which, after the teeth 126, has passed it, springs up into position behind the tooth and prevents its ret rn movement.

Some of the parts which have been above described for the intermediate Wheels are not necessary for the terminal wheels. Thus, for the first wheel on the right the swinging arm 150 to the right of said wheel is not necessary. Its place is taken by a fixed arm 169 whichcarries a pawl 170, the function of which is merely to engage the teeth of the wheel and thereby center the same. In

both terminal wheels the inner sleeve 116 I totalizers 113, the shifting of said totalizers carrying the two pins is not necessary,.-but the first wheel 120 on the left only has a pin, and this pin is secured directly to the wheel 120 thereof. In like manner the wheel on the extreme left is not required to have an arm projecting from the sleeve.

From the above description the operation of the machine will be seen to be-as follows: If a check or pass book is to have an amount printed thereon, the sheet of paper to be I printed upon is inserted in the slit 42 of the casing of the machine, whereupon the proper keys for entering the amount in the V book will be depressed by the operator.

4 sition, (note the right hand portion of Fig.

,6) and at the same time the cams 93 adja- The depression of each key is followed by the locking of said key inthe depressed pocent each of the other keys of that column lock said keys in the raised position. The depression of. any key in a column depresses the bar 7 7 at the same time which causes the depression of all of the'terminal stops of that column, so that they will not interfere with the operation of the slide 31 upon the operation of the machine. At the same time, assuming the amount $400 to be written, the termlnal stop at the left of the column in which the 4 is depressed will be depressed so that the dollar sign will be printed upon the type Wheels 36, while at the same time all of the terminal stops at the right of the 4 will be so depressed that each of those type wheels at the right of the 4 will print the zero. Note for the operation of the bars 77 Figs. 1, 2 and 3.

'Upon the setting of the keys, the handle 12 may be pulled forward. The first operation of the handle is to set the slides'31 in such a position as isdeterminedby the terminal stops and the key stops, the accumulation of the increment of movement :of each slide being effected upon the totalizer set 113. As the .-l1andle 12 is moved forwardly and downwardly, the pawl passes the projection 68 of the hammer 66. Also during the travelof the handle 12, the pawl 49 pushes against theroller 48 until it passes the same. When both of these pawlsslip off the parts with whichthey contact the platen 43 and hammer 66 will cause impressions to be made at the two printing places, whereupon the handle 12 may be permitted to return to its initial position, and as it returns to the cam 116 and finally passes through the slot 108 to permit the return of the depressed key to its initial position. In this manner the teller may keep an exact record of every amount for which he is responsible upon thestrip 62, and at the end of any period he may ascertain the total thereof by shifting the totalizers 113 downwardly into contact with the rack 118.

When the total is to be taken from the into connection with said rack .118 causes the cam 129 to shift the shutter 109 up across the opening 42', thereby preventing the insertion of a check therein. The lever 45 at the same time shifts the printing mechanism adjacent the'wheels 36' dowhwardly so that the pawl 49 cannot cause an impression to be made by said wheels.

-After the totalizers 113 have been set to whereupon the machine may be used as an ordinary adding machine without, in any way, interfering with the total accumulated upon the totalizers 113. When so. set for operation as an ordinary adding machine, the cam 99 will close the slit 42 and will prevent the platen 43 from printing from the set of wheels adjacent the same, in the same manner as when the totalizers are set down against the rack 118 for the purpose of" printing a total therefrom.

Further explanation is not given of the operation of the totalizers themselves for the reason that they may be of several different forms, but it is necessary to point out that some locking device is necessary to prevent them from spinning should .the machine be operated too rapidly, and

this device comprises the pawl 164, which places such resistance upon the movement of the gear wheel 120, as may be necessary to prevent undue movement thereof, no matter how fast the machine may be operated.

It is to be here noted that the only time the slit 42 is open so that the operator can print from the type wheels 36 is when the.

totalizers 113 are so set as to accumulate thereon amounts printed by said printing wheels. That is to say, that if a total is to be taken from said wheels no printing can be done thereby, nor can any printing be done from said wheels unless the totalizers 113' are out of use, since in both the intermediate and lower positions of said totalfor simultaneously moving said recording devices and also the operative series of ac cumulators through variable distances in correspondence with the particular keys depressed in the corresponding columns, substantially as described.
